AUTOMATIC LUBRICATOR FOR RAILROAD-CAR AXLES.

Specification of Letters Patent No.

To all whom it may concern: Y

g Be it known that I, MICHAEL EGAN, of Ogdensburg, in the county of St.Lawrence and State of New York, have invented a new and useful Devicefor Supplying Oil to the Axles of Railroad-Cars and other Journals,which I have described in the following specification and accompanyingdrawings with sulficient clearness to enable others of competent skillto make and use my invention.

My invention consists in the combination of a pin set eccentrically inthe end of the axle, an arm or slide, which is operated by said pin todip in the grease in a chamber below the axle and raise the grease tothe axle in the manner hereinafter set forth.

In the accompanying drawings Figure l is a perspective view. Fig. 2 is atransverse section. Fig. 3 is a longitudinal elevation showing the boxor oil chamber in section. Fig. 3 is an elevation showing in detail theplate A, and the arm B, said view being transverse to the axle. Fig. 5is a longitudinal detail elevation of the same parts and some otherswith which they are connected.

The axle may be constructed in the usual manner for outside bearings,and the oil box with square sides and bottom. A pin D is seteccentrically in the end of the axle, and a connecting rod C extendsfrom this pin to the Vring I-I which is attached to the arm B whichbeing thus connected to the pin D is caused to have a reciprocatingvertical 13,749, dated November 6, 1855.

motion as the axle revolves, and vthe hori` Zent-al part of the arm B isalternately plunged 1n the oil or grease below the axle, and ralsed upnear enough to the journal to brin some textilestlif'flvith which thispart of the arm should be coveredirlciita'ct L In the summer lard may beused to advanf tage-in the winter oil.

I do not claim in general terms feeding oil to the axle by anintermittent motion of the feeder' or feeders produced by the revolutionof the axle, or otherwise; neither do I claim the employment of afeederl which by either a constant or intermittent motion receives oilfrom a reservoirbelow, and deposits it on the axle.

I claim- The arm B placed under the bearing and made to descend into thegrease and rise to the ournal at each revolution of the axle by beingconnected to the eccentric D or its equivalent substantially as hereinset forth.
